"He's become radical here in the last couple of years," said Lockhart. "The problem I have with him is he doesn't know if he wants to be a white supremacist, sovereign nation or Muslim." He's got the literature for it and he's got the dress for it, but it's a little confusing."

According to arrest reports from the Sebastian County Sheriff's Department, Alan Crawford was arrested last week after he threatened to kill a car salesman in Fort Smith.

"It appears to me he wants to make news and he wants to be on the news for some reason," said Lockhart.

The sheriff said his office was contacted by an FBI agent from Chicago in November.

The agent was alerted to possible threats Alan Crawford had made to do something to make national news at the memorial service for Msgt. Joshua Wheeler.

Wheeler served 14 tours in Afghanistan and Iraq. He was killed rescuing 70 hostages from Islamic State militants in Iraq. A memorial service for the fallen hero was held in Muldrow, Oklahoma.

Lockhart said flyers were passed out to law enforcement officers who attended the service. The flyer pictured the Crawfords and alleged the couple had made credible threats to so something at the memorial service.

But the couple never appeared the memorial service.

Lockhart said the flyer was not released publicly, but it was widely circulated after someone took a picture and posted it on Facebook.

Lockhart said the couple was never arrested because they never broke any laws.

Now recent threats have the couple behind bars.

"When he gets on Facebook and makes threats, he and his wife, we're going to take it serious," said Lockhart. "You're not going to make threats over the internet without drawing attention, so he's getting attention, but he may not like the attention he's getting."

In addition to charges in Washington County, Alan Crawford is facing a felony terroristic charge in Sebastian County.
